2.2.5 Laser Surface Height Detector
The laser is used to detect the point where the upper surface of the product is; this data is used to
calibrate the relative dispense height of the nozzle. The unit is automatically adjusted in software
and carries out its own calibration cycle as part of the set up routine. The LED’s on the front of the
unit can be ignored and the yellow button must not be adjusted.
2.2.6 Auger Motor
The auger motor drives the screw in the auger valve; the number of turns is set by a feed para-
meter in the software. The screw provides control over the amount of adhesive to be deposited and
‘works’ the adhesive to pre-condition it. This ensures that at the correct height, the nozzle deposits
a precise amount of adhesive to the product surface and flow is maintained throughout the deposit
cycle.
2.2.7 Z Axis Motor
The z axis motor drives the unit to this calibrated location. An end stop dowel provides a stall point
for the motor upper limit (see graphic). Refer to the Calibration section of this manual for details on
setting the calibrated heights for deposit and idle heights.

2.2.8 Control Interface
The control interface is situated on the frame at the rear of the printer. Next to this, is the pneumatic
air regulator, which supplies the air pressure to the syringe.

2.3 SOFTWARE INTERFACE
The software is configured into two sections; the machine parameters are set in Maintenance and
the product parameters are set up in Setup Product.
2.3.1 Parameters
Before proceeding:
1. Camera reference point calibration must be carried out.
2. The product board, if loaded, must be unloaded.
3. The tooling must be set up initially as follows:
– Stinger Home
– Camera to Reference Dot Position
– Rising Table from Home to Vision Height
To set product parameters:
1. Select Setup Product.
2. Select Options.
3. Select Stinger Dispenser.
A parameters page is displayed for editing the parameters that apply to all sites.
4. Ensure that Stinger Dispense is set to Enabled.
5. Select Accept.
6. Select Back.
7. Select Back.
8. Select Back.
